feat(release): Ruleset-aware push with PR creation fallback

[thomas-vilte]

Description

I've improved the release command's resilience when pushing changes to a remote repository protected by GitHub rulesets or branch protection rules.

Specifically, when a direct git push (for commits or tags) is rejected by a ruleset, the system now detects this specific error (ErrPushRejectedByRuleset). For the release command's final push, if the direct push fails due to a ruleset, it will now automatically create a new branch (matecommit/release-vX.Y.Z), push the release changes to this new branch, and then open a Pull Request into the original base branch. This allows the release process to continue through a PR merge.

Additionally, I've updated the UI to display the specific stderr output from Git when a ruleset rejection occurs, providing clearer feedback to the user.
